Hello, You use the WAGOUpload tool. You can download it on the download center of WAGO. Make a backup and restore it on the new device. (if can check the remanent data to copy the persistent variables if necessary) You can also use a SD card, go to the WBM copy it the image to the SD card and restart the other controller on the SD card. In the WBM, copy it back to the internal flash. If you contact your local Wago office, they will more than probably help you. There is also a WAGO forum. RP,

Post by damian177 on CM4S GPIO's in Codesys ^{CODESYS Forge talk (Post)}
Hi, I am running my application on device based on Compute Module 4S (Cortex-A72 (ARMv8) 64-bit ). On this device I installed RPi Runtime in 4.11.0.0 version. In my project I use device: Codesys Control for Raspberry Pi 64SL and my project works, but I actually do not have acces to all GPIO's , because GPIOs Compute Module is available only in 3.5.16.0 version and it doesn't work. Properly work GPIOs B+/Pi2 but using this device I do not have acces to all GPIO's in CM4S. Anyone of can tell me how add GPIOs Compute Module 4.11.0.0 to my project ?

Post by jaspergain on Non-existing identifiers ^{CODESYS Forge talk (Post)}
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Post by starmaxou on How to download dependencies packages for CODESYS Control for Raspberry Pi SL ? ^{CODESYS Forge talk (Post)}
Hi everyone, I'm trying to install the CODESYS Control for Raspberry Pi SL package. The computer with CODESYS software is offline for security reasons. So, I downloaded the package on another computer and installed it manually. But this package has dependencies packages: CODESYS.Control SL Extension Package, V4.0.0.0 CODESYS.Control SL Deploy Tool, V4.10.0.0 As I said, the computer with CODESYS is offline. I cannot use the package installer to search for these packages. I did not find them in Codesys Store with another computer. Do you know where to find and download them? Thank you in advance for your help!

Post by timothyzalusky on Strange Behavior on Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I am seeing some weird runtime behavior related to the EQ function on a rapsberry pi based system. I have attached a screenshot showing the strange latching I am seeing on the EQ function, and I have not seen this behavior before. I tried freshly restarting the runtime and it has this same behavior. Anyone seen this? I am on 3.5.20 with the latest runtime installed. Basically, as soon as it hits one of those EQ's in the program, it latches effectively locking the output on. Any input from the Codesys team would be appreciated as well as anyone that might know what I am seeing.

Post by hwopereis on How to use Application Trigger in Modbus TCP Server ^{CODESYS Forge talk (Post)}
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

Post by joschi2804 on Licensing info not available. ^{CODESYS Forge talk (Post)}
Hi, maybe this fixes your problem. At least this was our issue back then. We tried to run the codesys runtime environment on an embedded Linux system. The problem on our side was that we changed the WORKDIR directory in the /etc/init.d/codesyscontrol script to /home/user/codesys, but we forgot to copy all files (including the hidden files) from the initial WORKDIR (I am not sure but I guess the initial WORKDIR was /var/opt/codesys) to the new one. After copying those files and restarting codemeter and codesyscontrol, we were able to upload licenses. Hope this help BR Josef

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.

Post by amy123 on Alarm Manager Example Alarm Client doesn't Populate ^{CODESYS Forge talk (Post)}
Hello, I tried to run the example project from https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/ However, I can not get the interface for Alarm History 12 Alarm Manager client to populate with any alarms. 'udiResult := AlarmManager.g_AlarmHandler.RegisterClient(itfAlarmManagerClient12, ADR(arritfAlarmsFromHistory12), iMaxCountAlarmsFromHistory12);' when I look at itfAlarmManagerClient12 its always empty. What is confusing is that when I simulate 2 alarms, iCountActiveAlarms 12 has a vlaue of 2, associated with itfAlarmManagerClient12 - so that appears to work. And yet, its useless as the ProcessAlarms Function can't extract anything from the empty array. I dont understand how these arrays are supposed to be populated and why its not working. Any help would be greatly appreciated!

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

I want to extract each element of an Array. Can someone help me with this. When I use JSONElementToString (part of JSON Utilities SL), I am seeing output as "ARRAY" instead of actual data.

Post by paulg on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!

Post by sangeetnenwani on Test Driver Availability in CODESYS 64-bit and Test Manager 5.1.0.0 ^{CODESYS Forge talk (Post)}
I’m operating with CODESYS in a 64-bit configuration and the Test Manager at version 5.1.0.0, where I’m attempting to use project scripts from an earlier version. These scripts call for certain test drivers that are not present in my installation. It’s unclear whether the absence is due to the 64-bit system, an update in the test drivers, or if I need to enable or install additional elements. For instance, the loadproject(Codesys.Base) command is missing, but loadproject(testmanager.project) is available. The FileIO command for CODESYS isn’t accessible, yet the testmanager’s driver for it exists, as does the execuptscript command.

Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}
Hi Everybody, I'm looking for a simple way of comparing two array of a structure. My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ?

Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hi, I am looking for exactly the same thing. I would think that using a layer 2/3 managed switch should work but I am not convinced. I would like to test it in order to see if it would be possible to run many Codesys Docker instances on a server and run only 1 ethernet cable from the server to a managed switch closer to the machines beeing controlled instead of having to run multiple long ethernet cables. I was going to buy a managed switch in order to test it but I want to first make sure it is possible and I want to figure out exactly what kind of switch I would need. Is this even possible? I think this is a feature that would be very useful paired with "Codesys Virtual Control SL". Thank you

Post by opineiro on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
Hi there, I have a Keyence bar code reader connected to my plc through Ethernet/IP. The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success). When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture) How do I manage this variable? Thanks!

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Hi everyone, I need some help with displaying an image (test.png) on my device. Initially, showing the image is straightforward. However, I want to be able to update the image dynamically. My goal is to send updated files via FTP to the device, and have the display automatically show the latest version of the image. All images will be sent with the same name (e.g., test.png). Currently, I can see the updated image after sending it via FTP and performing a warm restart, but I'd like to achieve this in runtime, without having to restart the display or application. Does anyone have suggestions on how to implement this? Thanks in advance!
